Price listed is for half an ounce of mixed acrylic beads. These are marbled blue acrylic beads made to look like a natural stone. They range in size from approximately 6mm to 10/7mm. The holes of these beads measure approximately 0.25mm but sizing may vary from bead to bead. Since they vary in size we cannot guarantee the number of beads you will receive, only the weight. The sample half ounce pulled had about 135 beads.
